Yesterday we announced the GA release of Percona Server 5.6, the latest release of our enhanced, drop-in replacement for MySQL. Percona Server 5.6 is the best free MySQL alternative for demanding applications. Our third major release, Percona Server 5.6 offers all the improvements found in MySQL 5.6 Community Edition plus scalability, availability, backup, and security features some of which are found only in MySQL 5.6 Enterprise Edition.

Percona Server 5.6 comes with:

• General performance improvements
• Extensive diagnostics via TABLE/INDEX/USER …

I occasionally see customers who are taking backups from their PXC clusters that complain that the cluster “stalls” during the backup.  As I wrote about in a previous blog post, often these stalls are really just Flow Control.  But why would a backup cause Flow control?

Most backups I know of (even Percona XtraBackup) take a FLUSH TABLES WITH READ LOCK (FTWRL) at some point in the backup process.  This can be disabled in XtraBackup (in certain circumstances), but it is enabled by default.

If you go to your active cluster right now an execute a …

Our commitment to drop-in compatibility with MySQL has important benefits for Percona Server users and drives our development process as I’ll describe.

I recently blogged on setting up Experimental Git mirror of Oracle MySQL trees up on GitHub. I’m now happy to announce that there are also mirrors for:

• Percona Server
• Percona XtraBackup
• Percona Playback

I’ve also updated the Oracle MySQL GIT mirror to include MySQL 5.7 and the (now abandoned) MySQL 6.0. I include the abandoned 6.0 tree as it can provide useful archaeology as to where some code came from.

I’d love to hear about any positive/negative experiences using these mirrors. Hopefully shortly I’ll fix up the last …
